Coccidian Prevalence and Intensity in Free-Ranging and Rehabilitating Wild Raptors

Abstract

[EN] Coccidians infect the intestines and other organs in vertebrates, causing pathogenicity ranging from asymptomatic infections to death. However, knowledge about coccidian infections is lacking for most free-living raptor species. Gathering basic information on coccidian infection would allow a better understanding of the basic ecology of raptors and would improve conservation actions. In this study, we assessed the prevalence and parasitic loads of coccidians in several free-ranging and rehabilitating wild raptor species in recovery centres in Spain and Belgium from 2015 to 2017. Faecal samples from 129 individuals of 17 different raptor species were collected. Coccidian oocysts were found in nine species. Significant differences were found in the prevalence of coccidians between the two countries, with higher rates in Belgium (45.0%) than in Spain (20.2%), as well as between age categories, with nestlings and juveniles showing a higher prevalence (30.5%) than adults (11.4%). Three different coccidian genera were identified. Caryospora spp. and Eimeria spp. were found in diurnal raptors and owls with medium/high loads (median ranging from 75-91344 ooc/g), while Isospora spp. was found only in Griffon Gyps fulvus and Egyptian Vultures Neophron percnopterus at low infection intensities (62-170 ooc/g). We present the first case of Isospora spp. in European vultures, although it is unclear if this is a true intestinal parasitisation or a pseudo-parasitisation with oocysts from livestock on which the vultures fed. Despite the limited sample size in our study, our results contribute to filling a gap in the knowledge of coccidian infections in wild birds.-Crespo-Ginés, R., López, D.S, Berriatua, E., Blanco, G., Candela, M.G. & Pérez-Garciá, J.M.

[ES] Los coccidios infectan el intestino y otros órganos en los vertebrados, causando patogenicidades variables que van desde infecciones asintomáticas hasta la muerte. Sin embargo, el conocimiento de cómo estas infecciones afectan a las diferentes especies de rapaces silvestres es escaso. La obtención de información básica sobre infecciones por coccidios permitiría comprender mejor la ecología básica de las rapaces y mejorar sus programas de conservación. En este estudio evaluamos la prevalencia y la carga parasitaria de coccidios en varias especies de aves rapaces en libertad y en proceso de rehabilitación en centros de recuperación en España y Bélgica entre 2015 y 2017. Se recogieron muestras fecales de 129 individuos pertenecientes a 17 especies distintas de rapaces. Se encontraron ooquistes de coccidios en 9 especies. Diferencias significativas en la prevalencia de coccidios fueron encontradas entre ambos países, siendo más alta en Bélgica (45,0%) que en España (20,2%), y también mayor entre pollos y juveniles (30,5%) que en adultos (11,4%). Se identificaron tres géneros de coccidios diferentes. Caryospora spp. e Eimeria spp. fueron encontradas con cargas medias / altas (mediana de 75-91344 ooc/g) en rapaces diurnas y búhos, mientras que Isospora spp. se encontró solo en buitre leonado Gyps fulvus y alimoche Neophron percnopterus a una intensidad de infección baja (62-170 ooc/g). presentamos el primer caso de presencia de Isospora spp. en buitres europeos, aunque no podemos determinar si se trata de una verdadera parasitación intestinal o de una pseudoparasitación con ooquistes de las especies de ganado de las que se alimentan. A pesar de que el tamaño de muestra en este estudio es limitado, nuestros resultados contribuyen a llenar un vacío en el conocimiento de las infecciones por coccidios en aves silvestres.
